Which superheroes are metal? If there was any debate about Aquaman, actor Jason Momoa may have just settled the argument. During a chat with Metal Hammer, Momoa revealed that he used the metal stylings of Tool, Metallica and Black Sabbath to inspire him to get into the character of Arthur Curry (aka Aquaman).

"Aquaman's pretty metal. I know no one thinks that, but Aquaman's metal," the actor explained. "I kind of build my characters off of metal songs. Conan (The Barbarian) was really heavy Pantera, I'd say Aquaman was probably mostly built out of Tool and (Metallica's) Kill 'Em All. 'Ticks and Leeches,' if I want to get specific. There's a lot of Sabbath in there too."

The James Wan-directed film finds Momoa as the heir to the underwater kingdom of Atlantis, but as the city prepares to rise again, he must find a way to unify his two worlds. The film also stars Amber Heard, Willem Dafoe, Patrick Wilson, Nicole Kidman and Dolph Lundgren.
